Abstract
To secure a favorable photographing state without causing an increase of power consumption. A blade opening/closing apparatus includes a magnetic driving portion including a coil to which a driving current is supplied and a magnet that is rotated along with energization to the coil; a driving body that includes a to-be-locked portion and is operated by the magnetic driving portion; an opening/closing blade that opens/closes an aperture by an operation of the driving body; and a lock portion that sets a locked state of the opening/closing blade by engaging with the to-be-locked portion, the setting of the locked state and a release of the locked state being carried out in accordance with a rotation position of the magnet. Accordingly, since the lock portion engages with the to-be-locked portion to thus set the locked state and unlock the locked state in accordance with the rotation position of the magnet and locking with respect to the opening/closing blade is not performed by a magnetic force of the magnet, a favorable photographing state can be secured without causing an increase of power consumption.
